This invention relates to weeding devices and pertains particularly to a devlce de-' signed for attachment to a cultivator used e rth and eirtract the weeds therefrom.

"inother object of the invention is to proweeding device ofsuch'a character number thereof may. be readily at- .che. to the cultivating machine to travel between the plows thereof when the sameare used for siding up the hilis, the weeders .raveling upon the hills between the plows to remove weeds therefrom.

The invention will be best understood m consideration of the following detailed description taken in connection with the accompanying drawing forming a part the present invention with the understanding, however, that the invention is not 1 to any strict conformity with the of the drawing but may be changed icd so long as such changes or modific; iarl; no material departure from the salient features of the invention as expressed in the appended claims. in the drawing ire l is a view in side elevation of the we embodying the present invention showing the same in association with a culti- 7 z'ator plow.

ure 2 is a top plan view of the present structure.

re 3 is a sectional view taken upon line -il of Figure 2.

Referring to the drawing in detail, Figure shows a portion of a cultivator framev 1929. Serial N0. 357,469.

l connected at the forward end by a cross tubular member or sleeve 5 through which cntendsla-shaft 6. Each end of the shaft upon the outside of the adjacent framebar' 4% extends through the hub 7 of a weeder wheel which comprises a pair of plates 8 arranged in side by side relation and carried bythe hub 7, and a plurality of radially disposed curved digging fingers 9. The inner ends of the fingers 9 are secured between the plates 8, these plates 8 being drawn together to hold the digging fingers 9 therebetween by a pluralityof transverse bolts 10.

Positioned between the rear ends of the side members lof the weeder frame is a weeder wheel which like the two at the front part of the frame consists of'a hub portion 11 'which comprises a 'pair of spaced circular plates 12 held in side by side relation by suitable bolt members and] gripping there between a radially disposed series of curved digging or earth penetrating fingers 13.

Each of the rails f has cast integral therewith'and projecting laterally therefrom and adjacent the forward end thereof a pin 14" which is detachably engaged in an aperture 16 on=the end of one arm of a two part U- shaped yoke member 15 which straddles the weeder frame in the manner shown. This two part ti -shaped memberis separated-at the central-portion of the yoke thereof, one of the parts having a "bar 16 projecting therefrom which is designed for engagement withthe cultivator beam lito which the plow 2 is attached, the other part of the yoke being detachahly secured to the bar by the bolt members 16 as shown in Figure 3.

The earth penetrating fingers 9 and 13 of the weeder wheels are so directed that as the wheels move forwardly they will enter the ground at'a rearward inclination coming up therefrom injsuch a manner asi'topiok or spade up the earththereby extracting any weeds which may be adjacent thereto.

As shown in Figure l, the fingers 9 of the front weeder wheels and the'fingers 13 of the rear weeder wheel are of sufficient length to overlap a substantial distance. r This device is designed to be used after the hills have been planted and beforethe young with a plurality of apertures, as indicated by reach a height of more than one inch.

y providing the side pieces of the yoke 15 the numeral 16", the device can be so adjusted that the fingers will penetrate the earth from 1'. to 3 inches so that the seeds in the ground over which the device passes will not be disturbed thereby. After the plants are up, the device can be run thereover to remove "weeds from the hills without fear of removing the plants as the weeder will not disturb plants having feeder roots.

By adjusting the U-shaped yoke 15 upon the lugs 14, as previously described, the depth of penetration of the fingers 9 and 13 can be controlled and also in view of the location of the lugs It, the bar 16 of the yoke will be maintained in normally Vertical position and the device therefore rigidly held against the ,While I have described the weeder wheels 8! enstructed of a series of units, that is, carrying hubs, retaining plates carried by the htlbeand fingers secured between the plates, it is, of course, to be understood that I do not W'mh to be limited to a wheel of this construction for it will be readily understood that these wheels may be of cast metal in which case the hubs, lates and earth penetrating fingers will be integrally connected.

Frmlthe foregoing description it will be readily seen that with a weeder device of the character {described a number thereof may be lttpched to a cultivating machine between the plows thereof to run upon the hills between which the plows pass removing weeds therefrom as the plows dig up the earth on each side of the hill in the usual manner.

Having thus described my invention, what I claim is a a 1,, A weeding attachment for cultivators, comprising a relatively long substantially U-shaped frame, means for suspending said frame in substantially horizontal position from a cultivator frame, said U frame having the olre portion formed to provide a sleeve, a shaft extending through said sleeve, a pair ofelements on said shaft, one at each end thereof each comprising a hub having a plurality of radially directed curved fingers setured thereto, and a rotary element mounted between the side members of said U frame at, the end remote from said sleeve and comar sing a hub having a plurality of radially I Iver: arcuate fingers extending there 9. weeder attachment for cultivators, comprising a horizontally disposed substantia 1y lJ-sha d frame having the yoke porti thereof formed to provide a sleeve, a 81in extending through said sleeve, a pair o ,rotar elements upon said shaft, one at each en thereof and each including a pluof radially disposed arcuate fingers, a sheft connecting the free ends of the arms of said frame, a rotary element mounted upon said last shaft and including a plurality of radially dis osed arcuate fingers, and a U-shaped memer disposed across said frame and having the free ends of the sides thereof pivotally attached to the adjacent sides of the frame and further having an extension for facilitating the attachment of the \veeder to a cultivator.

3. A weeder attachment for, cultivators, comprising a substantially U shaped frame normally disposed in horizontal position, a shaft extending across the closed end of the frame and carrying a rotary element u 11 each end, each element includin a plurality of radially extending arcuate ngers, a rotary element disposed between the side members of the frame at the other end thereof and including aplurality of radially disposed arcuate fingers, a lug extendin later ally from each side of said frame, an means for connecting said frame to a cultivator frame, comprising a substantially U-shaped member disposed across said frame and having the free end of each side thereof over lyi the lug of the adjacent side member of the rame and formed to receive the same and further having an extension from the closed end thereof for attachment to the cultivator frame. y

In testimony, whereof I hereunto afiix my signature.
